Comprehensive Specification, Applications, Advantages, Related Models, and FAQ
The Bently Nevada 330104‑00‑15‑10‑01‑CN is an industrial-grade eddy current proximity probe designed for non-contact measurement of shaft vibration, displacement, and position in rotating machinery. It belongs to the 3300 XL 8 mm probe family, widely recognized for high reliability in machinery monitoring systems across power plants, petrochemical facilities, and heavy industry.
This model features a Chinese standard configuration (“CN”) optimized for installation, connectivity, and cable routing according to regional requirements. The probe uses a precision coil to detect eddy current changes caused by shaft motion, producing a voltage signal proportional to the gap. This signal interfaces with machinery protection and condition monitoring systems for real-time fault detection and trend analysis.
The 3300 XL series is designed for high-precision, long-term operation in harsh industrial environments. It supports machinery protection systems that detect imbalance, misalignment, rubbing, looseness, and bearing deterioration before critical failures occur.
A global leader in condition monitoring and machinery protection, this brand is synonymous with durability, precision, and long operational life in heavy industrial environments.
